Melatonin and the Human Hair Follicle.

BACKGROUND: Melatonin, a pleiotropic hormone, affects the physiological processes including that of the hair follicle. We seek to identify the scientific evidence to support the potential benefits of melatonin in human hair growth. OBJECTIVE: To summarize the evidence on the association between melatonin and hair health, denoted by hair growth. METHODS: A literature review using 3 databases (PubMed, Google Scholar, and Cochrane) identified studies investigating the relationship between melatonin and hair loss (2022). The following search terms were used: (hair OR hair loss OR alopecia OR hair growth OR effluvium OR scalp) and (melatonin). Two independent reviewers screened studies for inclusion criteria, and data collection included demographics, melatonin intervention, study type, and effects on hair. RESULTS: A total of 11 human studies were identified with evidence of melatonin use in subjects with diagnosed alopecia (2,267 patients; 1,140M). Eight of the studies reviewed observed positive outcomes after topical melatonin use in subjects with androgenetic alopecia (AGA). Most studies report improved scalp hair growth (n=8), density (n=4), and hair shaft thickness (n=2) among melatonin users compared with controls. Effective topical melatonin dosage appears to be 0.0033% or 0.1% solution applied once-daily for 90 to 180 days vs 1.5 mg twice-daily oral melatonin supplementation for 180 days. CONCLUSION: There is evidence to support melatonin use to facilitate scalp hair growth, particularly in men with AGA. Further studies should include more patients and investigate the mechanism of action. J Drugs Dermatol. 2023;22(3): doi:10.36849/JDD.6921.

Utilization of Telehealth Solutions for Patients with Opioid Use Disorder Using Buprenorphine: A Scoping Review.

Background: A scoping review was conducted to examine the breadth of evidence related to telehealth innovations being utilized in the treatment of opioid use disorder (OUD) with buprenorphine and its effect on patient outcomes and health care delivery. Materials and Methods: The authors systematically searched seven databases and websites for peer-reviewed and gray literature related to telehealth solutions for buprenorphine treatment published between 2008 and March 18, 2021. Two reviewers screened titles and abstracts for articles that met the inclusion criteria, according to the scoping review study protocol. The authors included studies if they specifically examined telehealth interventions aimed at improving access to and usage of buprenorphine for OUD. Results: After screening 371 records, the authors selected 69 for full review. These studies examined the effect of telehealth on patient satisfaction, treatment retention rates, and buprenorphine accessibility and adherence. Conclusion: According to the reviewed literature, incorporation of telehealth technology with medication-assisted treatment for OUD is associated with higher patient satisfaction, comparable rates of retention, an overall reduction in health care costs, and an increase in both access to and usage of buprenorphine. This has been made possible through the expansion of telehealth technologies and a substantial push toward relaxed federal guidelines, both of which were quickly escalated in response to the COVID-19 pandemic. Future research is needed to fully quantify the effect of these factors; however, the results appear promising thus far and should urge policymakers to consider making these temporary policy changes permanent.
